Every little bit helps
I have had k&n in air raid air intake systems before and never really noticed any difference in performance on my vehicles but after installing my volant on my excursion i was highly impressed. I noticed a difference right away especially in torque. I also picked up some extra mpg. I pulled my 30' travel trailer last week and went from 8 mpg to 9.5-10 doesn't seem like much but when you factor in im driving a heavy suv with a v10 and pulling another 5k plus pounds behind me the extra mpg, horsepower, and torque from a air intake its well worth it.
